Over the years, since circa 1984, I've done extensive research on this and related titles. Turns out this book is a compilation of individual articles written by Clara Bloomfield-Moore and published by her in diverse magazines of that time period. An effort was made to find the original articles. While most were found some were not. These original articles were edited; i.e., important details in the originals were edited out when compiled into this book. With this in mind I found, scanned/typed and republished those original articles that the original material is not forever lost. Check this page for articles by Bloomfield-Moore especially where article titles match chapter titles in this book.
